Mitral valve repair is increasingly preferred over replacement for mitral regurgitation, offering better long-term outcomes and fewer complications. This approach preserves heart function and improves survival rates.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Valve Repair
  • Thoracic Surgery

Background:

  • Mitral valve reconstruction was initially favored but later overshadowed by prosthetic and bioprosthetic valves.
  • Long-term studies revealed suboptimal complication rates and durability issues with prosthetic and bioprosthetic mitral valves.
  • Advancements in annuloplasty rings and standardized repair techniques have improved the reliability and reproducibility of mitral valve repair.

Purpose of the Study:

  • To highlight the resurgence and advantages of mitral valve reconstruction over valve replacement.
  • To discuss the diverse techniques employed for various mitral regurgitation pathologies.
  • To present comparative outcomes of mitral repair versus replacement.

Main Methods:

  • Review of long-term follow-up studies comparing mitral valve repair and replacement.

  • Analysis of complication rates, survival, thromboembolism, reoperation, infective endocarditis, and valve-related complications.
  • Evaluation of the impact of preserving native valve structures (papillary muscles, chordae tendinea) and avoiding foreign materials.

    • Main Results:

    • Mitral repair techniques, utilizing annuloplasty rings, demonstrate universally reliable and reproducible excellent results.
    • Outcomes for mitral repair, including hospital mortality, survival, and freedom from major complications, favorably compare to mitral valve replacement.
    • Preservation of native structures and avoidance of foreign materials in mitral reconstruction enhance systolic function, improve survival, and lower complication rates.

    Conclusions:

    • Mitral valve reconstruction is a viable and often superior alternative to mitral valve replacement for managing mitral regurgitation.
    • The expanded indications for mitral repair encompass a wider range of lesions and earlier surgical intervention due to improved results and technical advances.
    • Mitral repair offers enhanced long-term benefits, including improved cardiac function and reduced complication rates, compared to valve replacement.
